D Correct answer
Explanation

Factoring the equation x^2 + 2x = 0 gives x(x + 2) = 0. Setting each factor to zero results in x = 0 and x = -2.

AI explanation

Factor the quadratic equation x^2 + 2x = 0 by factoring out x to get x(x + 2) = 0. Setting each factor to zero gives x = 0 and x + 2 = 0. Solving the second equation gives x = -2, making the roots 0 and -2.
